Experimental Investigation on the Damage Characteristics of Typical Body Armor by the After-effect Fragments of Bullet

doi:10.3969/j.issn.1000-1093.2019.11.023

Abstract

Abstract: In order to explore the killing ability of the after-effect fragments of bullet, an after-effect experimental was carried out based on an armor-piercing bullet with tungsten alloy penetrator, 10 mm-thick homogeneous steel plate and a typical polyethylene composite body armor. The mass distribution and dispersion law of after-effect fragments and the penetration effects of after-effect fragments penetrating into body armor at different velocities are analyzed. The results show that the mass distribution range of after-effect fragments is larger; the dispersion radius of after-effect fragments at 1.4 m from the protective steel plate is 21.3 cm; the failure mode of body armor is dominated by shear failure, and at the same time, it is accompanied by the melting and burning damages. The boundary between penetration holes is torn due to the boundary intersection, and a large open gap is formed to develop tear propagation and exacerbate the damage. Key

Key words: bullet, after-effectfragment, bodyarmor, penetrationdamagecharacteristic, polythenecomposite
